Abstract
This communication device comprises a control circuit and a transmission circuit. The control circuit determines which of a plurality of communications to be prioritized, that include transmission and/or reception of information to adjust the use of resources between communication devices in side link communication. A communication circuit performs communication in accordance with the determination of the control circuit.
Claims4
A first user equipment (UE) comprising:
- a receiver, which, in operation, receives a first Sidelink Control Information (SCI) format including a first priority value and a first reserved resource for Physical Sidelink Shared Channel (PSSCH) transmission from a second UE and a second SCI format including a second priority value and a second reserved resource for PSSCH transmission from a third UE;
- circuitry, which, in operation, detects the second priority value of the third UE is smaller than the first priority value of the second UE, and determines that the first reserved resource and the second reserved resource overlap in time and frequency;
- and
- a transmitter, which, in operation, transmits conflict information to the second UE of the first priority,
- wherein the second priority value of the third UE smaller than the first priority value of the second UE indicates that the second reserved resource for PSSCH transmission from the third UE has higher priority than the first reserved resource for PSSCH transmission from the second UE.

A communication method for a first user equipment (UE), the communication method comprising:
- receiving a first Sidelink Control Information (SCI) format including a first priority value and a first reserved resource for Physical Sidelink Shared Channel (PSSCH) transmission from a second UE and a second SCI format including a second priority value and a second reserved resource for PSSCH transmission from a third UE;
- detecting the second priority value of the third UE is smaller than the first priority value of the second UE;
- determining that the first reserved resource and the second reserved resource overlap in time and frequency;
- and
- transmitting conflict information to the second UE of the first priority,
- wherein the second priority value of the third UE smaller than the first priority value of the second UE indicates that the second reserved resource for PSSCH transmission from the third UE has higher priority than the first reserved resource for PSSCH transmission from the second UE.
